Colonoscopy Perth

Colonoscopy: Preparation, Procedure & Medications

Colonoscopy is a common procedure that examines the lining of your large intestine (colon) for abnormalities. This is performed by inserting a thin flexible tube fitted with a  light and camera through the anus and slowly advancing it into the rectum and colon. This instrument, called a colonoscope, and it will allow Dr Andrew Kiyingi to view images on a video monitor. During the procedure, the colonoscope will bend to follow the path of your gastrointestinal tract and blow some air to provide a clear view. The procedure is performed under twilight anaesthesia so you will be comfortable and unaware. A medical typed report of the procedure will also be sent to your GP and specialist.

  • Colonoscopy may be recommended as a screening test to check for early signs of cancer in the colon and rectum.
  • Assessment of abdominal pain, bleeding from the bottom (rectum), low iron (anaemia) or unexplained weight loss.
  • Assessment of unexplained changes in bowel habits and bowel blockages.

Dr Andrew Kiyingi will provide you with clear instructions to ensure that the colon is completely clean for the procedure to be accurate. This colon cleansing routine will involve dietary restrictions, oral fluids and special laxatives during the 1-2 days prior to your procedure. It is important to follow these instructions carefully.

Polypectomy: Preparation
Polypectomy: Preparation

Polyps are fleshy growths in the colon lining that are usually benign (noncancerous) and vary in size. We can’t always tell a benign polyp from a malignant (cancerous) polyp by its outer appearance. Polypectomy involves removing polyps during your colonoscopy. Because cancer can begin in polyps, removing them is an important means of early diagnosis and preventing colorectal cancer.


An empty stomach allows for the best and safest examination. You will be provided with specific fasting instructions.
